What is the purpose of C++ websocket?

C++ WebSocket is a protocol used for achieving bidirectional communication on the internet. It allows for real-time data transmission between client and server without the need for separate HTTP requests.

The functions of C++ WebSocket include:

1. Real-time communication: WebSocket offers a real-time, bidirectional communication mechanism that allows the server to actively push data to the client without the need for the client to constantly send requests.
2. Low latency: Compared to the traditional HTTP request-response model, WebSocket can reduce delay and provide faster communication speed.
3. Efficiency: The WebSocket protocol uses binary format to transmit data, which is more efficient compared to the text format.
4. Cross-platform compatibility: C++ WebSocket libraries often have cross-platform support, allowing them to be used on multiple operating systems and providing greater flexibility.
5. Real-time web applications: WebSocket can be used to develop real-time web applications, such as chat applications and collaborative editing tools, allowing multiple users to share information in real time.
6. Game Development: WebSocket can be used in game development to achieve real-time game updates, multiplayer game interactions, and other functionalities.

In conclusion, the purpose of C++ WebSocket is to provide a real-time, efficient bidirectional communication mechanism that can be applied in various fields of application development.
